Abstract
A device for relative movement of two elements comprises at least two first links, which are connected relative to a first of the elements via hinges and which are pivotable in substantially parallel planes relative to the first element under influence of at least one first power-exerting member. At least two second links, which are connected relative to a second of the elements via hinges, are pivotable in substantially parallel planes relative to the second element under influence of at least one second power-exerting member. The two first links form a first four-hinges system. The two second links form a second four-hinges system. These two four-hinges systems are coupled in series to each other between the first and second elements.
